Just to make this clear:

You can't tell if this is true or not unless you actually measured the current drawn from the devices and the current the hub provided. You could have very well overloaded a hub, but that hub could have limited the power (or even disabled power due to it detecting an overcurrent). Especially in the limiting case there is no way to recognize the situation easily.

So please, be careful telling not having found "this" to be true.

Edit: The point is that the device that is drawing power is responsible for not drawing too much power. Other devices can get damaged if a device is violating this. dangerousprototypes has a nice read on this.

rbhawaii:
very good information thank you for that bluebrother

torne:
That kind of warning is really not actually helping; it's equivalent to saying "Some people feel playing russian roulette is dangerous, although I personally have not gotten shot yet" :)

It *is* dangerous, with certain devices, hubs, or hosts, under certain conditions. I know this is true not because of some theory but because I have damaged things, melted them, or set them on fire this way on multiple occasions. There have been numerous instances where laptop models have been recalled because their USB host ports do not limit current correctly and a number of their users have had fires as a result of badly behaved devices being plugged into those badly behaved host ports.

So yes, it's possible that the devices/hubs/hosts/cables/etc you have are never going to be a problem. It's also possible that the *very next person to read your advice* will burn their house down (yes, this kind of thing really has burnt down houses).

I'm not going on about this because I really think the risk is high; if I thought it was, I wouldn't've provided the option in the first place. It is very low. But, your statements continue to suggest that you think the risk is a matter of opinion or personal experience, and that's just not true.


The manual explains how to use the battery bench plugin.

i have removed the last 3 lines from my first post altogether

this topic was intended to be a joyful discussion of how i accidentally discovered that there are now 1300mah batteries for the ipod  and additionally a 256gig ssd hard drive that works for the ipod - which is very exciting to me thats why i posted it to share with the rest of the world.

it has since taken a severe turn in another direction with me being a bad guy. if i knew something was dangerous i would not have done it nor posted others to do it.  i have had no problems with anything i have set my ipod to do but if you say its bad i will honor your knowledge since you obviously know more about this then i do.

i would suggest changing the names of the settings
from off , on , force to off, pc, wall . also mentioning possible fire situation when set to force/wall in the manual

kind regards guys

Just to make this clear: this is not about you being (or making you) the bad guy. However, since this is a public forum others might read some advice in this thread that can actually cause major problems so people were trying to make it absolutely clear what the risk is. Whoever wants to take the risk is free to do so, but obviously should be aware of the it.
